Required information Fruit flies normally have red eyes. Seven different true-breeding strains of fly with white eyes have been identified (A-G). In each strain, the white eye trait is due to an autosomal recessive allele. It is possible all seven strains have mutations in the same gene. Alternatively, they may have mutations in different genes. To determine how many genes are involved in eye color...

Researchers investigating chromosome 9 of com, Zea mays, found four mutations. Interested in finding the relative locations of the four mutations, they bred two different triple mutant strains. One of the strains displayed phenotypes of male sterility (ms), white endosperm cap (wec), and brown midrib (brm). The other strain displayed the phenotypes of male sterility, white endosperm cap, and brittle stalk (bst). They crossed both mutant strains with a true breeding wild type strain to create two F, hybrids. They...

Design a series of crosses in which you can tell a fly with a lobe allele, but a wild type phenotype, from a true wild type fly. Hint: Lobe is a dominant autosomal allele that exhibits variable expressivity, in which the eye size and number of facets is reduced; the eye may also have a nick or nicks in the edge in this mutant. Lobe also demonstrates incomplete penetrance; in the true breeding strain, the eye may also be wild...

You are working with the fruit fly that generally exhibits a brick red eye color (wild-type). In one stock vial you recover an eye color mutant with brown eyes that you use to eventually derive a pure-breeding brown-eyed stock. Your friend, performing independent studies on the fruit fly, also recovers a pure breeding brown eye color mutant that is phenotypically identical to your strain. How would you go about determining if the two pure-breeding brown-eyed mutant strains represent mutations in...

Some fruit flies have an autosomal mutation that causes the recessive white-eyes to appear compared to the wild-type (dominant) red eyes, while others have an X-linked mutation that causes the same varieties. You are presented with two populations of flies in unmarked tubes: one that has the autosomal white-eye mutation, and a population that has the X-linked mutation for white-eye. Assuming you have separated the pure breeding red and white-eyed parents in each population, What is the set of two...

In Drosophila, the X-linked recessive mutation vermillion (v) causes bright red eyes, in contrast to the brick-red eyes caused by the wild-type allele. A separate autosomal recessive mutation, brown (bw), causes flies to have brown eyes. Flies carrying both mutations have no eye pigmentation and are white-eyed. Determine the F1 and F2 phenotypic ratios for each sex from the following crosses: (a) brown females X vermillion males (b) white-eyed females X wild-type males
